Thicker than Water (The Shadow Acts Book 1)

What's worse than a cold latte?
Demons.
Welcome to Sydney, where infernal creatures, witches, templars, and soy lattes inhabit the same cafes. Reluctantly.
After Julien (an arts student, and ideal demonic host) witnesses a strange girl jump off a bridge - and survive - he is unwillingly drawn into an (unpaid) investigation of the occult murders occurring in the city.
He's joined by a templar, a demon-turned-almost-human, and a barista who may-or-may-not be angelic. The four unlikely allies fight to eliminate the infernal threat before their own dark pasts are revealed.
